I have a script that does this for instance:

curl --output /tmp/S201008112_NCEP.MET.temp http://oceandata.sci.gsfc.nasa.gov/cgi/getfile/S201008112_NCEP.MET

However, I am getting back:

file /tmp/S201008112_NCEP.MET.temp
/tmp/S201008112_NCEP.MET.temp: ASCII English text

which contains:
cat /tmp/S201008112_NCEP.MET.temp
Apparently, the file you seek already being delivered.

If you are using a download accelerator, please stop.

If not, please wait 30 minutes and try again

Can you tell me what this means?

Thanks,
brock
